[MC-6600] Hoppers makes items jump when they dont fit in the hopper

So when you have several hoppers next to each other in a sorter... Items tempt to go flying... Because if the item doesnt fit in there it jumps ump and maybe skips it good place. So this makes sorting machines only work at 95% can you guys fix that?

Havent noticed this behavior are you sure its not jumping on a stair or half slab? Which is a different bug.

Watch my video on automatic tileable sorting machine:

Its a great machine... But if a hopper has like cobble in it and dirt tries to go in. It checks in like 1 tick and if it ain't fitting in there it litterally JUMPS up and keeps the velocity it was going in. Wich may screw it up becus the next hopper maybe have the right item in where it fits in. But then it jumps over it because of that. Hope you understand

at which time mark can i find it?

Thimo Franken 2013-01-08T20:01:45Z

What do you mean?

That happens because the hopper has a composite hitbox. The item tries to fall on the carved middle, but can't occupy that space due to the new item ejection code so it jumps. Similar behavior can be seen with the lower step of a stair block.

Yeah well this behaviour makes it impossible to have a 100% reliable tileable item sorting machine D: So mojang please improve our abilities and remove that hitbox thing

Ultimate Omicron 2013-01-08T21:55:19Z

For now you can use detours and space between the hoppers. Are you using water to transport the items?

Thimo Franken 2013-01-09T06:38:23Z

Yeah but i finally got a proper way of tiling the sorters as i shown in my video... but because of this behaviour it aint possible to get that working 100 percent

Confirmed in 13w02b.

Thimo Franken 2013-01-12T08:40:09Z

Thanks Tails 🙂

I think thats why its called a "Hopper"

Thimo Franken 2013-01-17T10:39:51Z

That's nonsense... It makes every thing really unreliable. So it shouldn't be intented behaviour.

Dragnoz 2013-01-17T10:44:05Z

😉 I do agree with you though and I did add my vote...

Corgano Wade 2013-01-21T04:28:08Z

It's annoying as hell! please PLEASE fix

Jesper the End 2013-01-23T09:59:17Z

Annoying indeed, but it probably works as intended. One weird thing I have noticed though, is that xp also bounces when it is on a hopper.

fuj1n 2013-01-24T11:59:33Z

This is a regression for items getting stuck inside transparent blocks, when items are inside those, they fly out, and when items are on top, they bounce, even if nothing occupies the way for the item to fall into the hopper, you can occasionally see the item bouncing away from the hopper before disappearing.

John White 2013-03-01T17:04:02Z

Appears worse in 13w09c than before. My sorter is missing huge amounts of items now, compared to the previous snapshots.

Jesper the End 2013-03-17T22:12:26Z

If you want a stable item sorter, It's way easier now. You don't have to use water, just use hoppers instead of water. Just search for it on youtube/google

I have a lavablade-and-player-attack mob grinder with a hopper collecting the loot, and it keeps making the experience orbs bounce up into the lava. I think at least 2/3 of the experience is getting lost this way.

Resolving to MC-1720.
